Polyol method synthesis and characterization of nanoscale Sb_2Se_3 wires

摘要

Sb_2Se_3 nanowires ([001] orientation) with diameter of ～100nm and high aspect ratio were successfully synthesized in large scale by a facile nonaqueous polyol method, where home-prepared NaHSe alcohol solution is used as selenium source and PEG-400 serves as an excellent solvent and structure director. The product was characterized by XRD, TEM, SAED, HRTEM, EDS and diffuses reflectance spectroscopy, respectively. The effects of the experimental conditions on the final morphologies were also investigated. The method is promising to be extended to synthesize other V_2VI_3 compound semiconductor 1D nanostructure.
